DEMCO Type DM Mud line Gate Valve

VigorPetro's DM Series Gate Valves are compatible with the original Cameron DEMCO valves. We can provide both Minor Repair Kit and Major Repair Kit for repair service.

Designed for dependable, heavy duty performance in abrasive service conditions, our DM gate valves are commonly selected for a number of oilfield applications, including:
• Drilling standpipe manifold • Pump manifold block valves • High pressure mud mixing lines
• High pressure drilling system block valves • Wellheads • Well treating and frac service
• Production manifolds • Production gathering systems • Production flow lines

     Flanged End                                      Butt Weld End                                Line Pipe Thread End

                  Hammer Union End                                                    Major Repair Kits

The seats are designed to provide a positive, tight shut off every closing cycle, even after long exposure to abrasion and scor-ing. Twin metal wear inserts, encapsulated in an elastomer, form a cylindrically shaped plug made up of a gate slot and two flowports. Once closed, line pressure forces the gate up against the downstream port seals which are tested up to 7,500 psi. The 4 in. 5000 Working Pressure (WP) thru 5 x 4 in. 7500 WP valve has a transparent stem cover which protects and reveals gate open/close position. Stem packing is self-adjusting on all sizes
